Description

  The present invention relates to a prism glass structure for daylighting used for floors such as skylights of buildings, stairs and corridors, ceilings of underground passages, outer walls and inner walls, and the like, and a prism glass used therefor and a manufacturing method thereof.

  The prism glass is a glass molded body having a bottomed and uncovered concave part, and has a square or circular top surface, a side wall surface extending downward from the periphery of the top surface, and an annular bottom surface. And the whole cross section is a glass block formed in a reverse concave shape. Also, it is thick and particularly sturdy, and can withstand strong impacts, so it can also be used for bridges and pavements and walk on it.

  In general, prism glass is set in an iron lattice frame and is used for taking natural light into a lower part of a building such as a ceiling, a veranda, or a basement, and has high light transmittance and diffusibility. In order to produce this, molten soda lime glass is put into a lower mold having a predetermined shape, and the upper mold is lowered from above, and then press molding is performed. The method of taking out and slowly cooling is taken.

  Such a prism glass is made of a transparent glass, and various designs are applied by engraving a predetermined pattern on the translucent surface, particularly the translucent surface on the inner surface side where the concave portion is formed. In recent years, with diversification of architectural design, Patent Documents 1 to 5 are disclosed.

For example, Patent Document 1 discloses a glass block in which a pair of transparent glass moldings having a bottom and a lid and having a recess are fused and integrated with each other at the open end edge, and the inner surface corresponding to the bottom surface of the recess. The thing in which the layer containing a luminescent substance is formed is disclosed. Further, Patent Document 2 discloses a glass brick having a bottomed, uncovered and recessed portion in which a layer containing a light-emitting substance is formed on one or both light-transmitting surfaces. In Patent Document 3, a glass molded body, which is a constituent element of a glass block, is formed of a transparent glass cloth, and a plurality of colors for forming a colored pattern on the inner surface of the bottom wall portion of the glass molded body. Sprinkle glass decorations and fuse them together. This colored glass ornament is composed of a plate-shaped glass piece, a rod-shaped glass body, or a spotted pattern unit glass body, and a production method is disclosed in which a luminescent substance is applied or mixed as necessary. In Patent Document 4, a glass molded body that is a constituent element of a glass block is formed of a transparent glass cloth, and a plurality of colored glass decorations are formed in the transparent glass cloth that forms at least the bottom wall portion of the glass molded body. Is disclosed. In the production, after supplying the molten molten glass lump into the female mold, a plurality of colored glass decorative materials for forming a colored pattern are arranged on the surface side, and the transparent molten glass lump is further formed on the surface side. A manufacturing method is disclosed in which, after being supplied, these are stretched by the female mold and the male mold to form a glass molded body. In Patent Document 5, a resin film containing a phosphorescent phosphor is formed on the side surface of a glass block body in which a pair of transparent glass molded bodies having a bottomed, uncovered and recessed portion are fused and integrated with each other at the open end edges. What is formed is disclosed.
JP-A-9-21206 Japanese Patent Laid-Open No. 9-21207 JP 2003-160999 A JP 2003-165730 A Japanese Patent Laid-Open No. 9-296559

  However, in Patent Documents 1 and 2, since the layer containing the light-emitting substance is formed using low-melting glass, it is necessary to raise the temperature of a transparent glass molded body having a bottom and no lid and having a recess. Since heating and gradual cooling are required in the step of forming the layer containing the substance and the coloring step, the production period is long, and there are problems such as difficulty in color management and increase in equipment costs. The coating methods of Patent Documents 1 and 2 also have a problem that the design is monotonous. Further, in Patent Document 3, it is necessary to disperse a colored glass decoration coated or mixed with a luminescent substance in a concave portion of a transparent glass molded body having a concave portion with a bottomless lid, and then the temperature must be increased. In No. 4, since the transparent molten glass lump is supplied into the female mold, the colored glass decoration raw material is arranged and stretched to be fused and integrated by molding a glass molded body. In the step of forming the layer and the coloring step, heating and gradual cooling are required, and time and cost are required for production. In addition, there are problems such as difficulty in pattern consistency management and color management. Further, in Patent Document 5, since a resin film containing a phosphorescent phosphor is formed only on the side surface of the glass block main body, there is a problem that the light emission efficiency is low and it is difficult to make it stand out sufficiently as a shining design. is there.

  In addition, the prism glass is a single plate glass, although it is thick, it has low heat insulation properties, and condensation may occur on the inner surface in winter. For this reason, there is a demand for improving the heat insulation property because condensation rarely leads to soiling indoor walls and floors.

  Further, the daylighting prism glass panel may be constructed in a place where an unspecified number of people walk on it. Therefore, the possibility that the prism glass is artificially damaged is increased. Since broken glass pieces may fall into the indoor side, there is a demand for measures to prevent the broken pieces from falling.

  In view of the above problems, the present invention has a short manufacturing period, easy color management, does not increase equipment costs, and can obtain the necessary daylighting properties even when colored, increasing the transmittance of the daylighting surface. Even so, it is an object to provide a prism glass that does not impair the light emission intensity, a manufacturing method thereof, and a prism glass structure.

  The prism glass according to the present invention is a bottomed and uncovered prism glass having a translucent top plate portion, a side wall extending downward from the periphery of the top plate portion, and an annular bottom surface of the side wall, A resin layer containing a luminescent substance is formed on the inner surface of the top plate portion.

  When the resin layer is provided on the outer surface of the top plate portion, there is a problem in terms of durability and fading as a light emitting layer. In the prism glass of the present invention, the resin layer containing a luminescent substance is not directly exposed to the external environment, and is provided on the inner surface of the top plate portion where there is almost no opportunity for direct contact with people or objects. is important. Further, when a layer containing a luminescent substance is embedded in an inorganic glassy layer or directly inside the glass, a high-temperature thermal process is required. In the prism glass of the present invention, the light emitting layer can be easily formed by including a light emitting substance in the resin layer.

  The prism glass of the present invention is preferably formed by forming a resin layer containing a luminescent substance on any of the outer surface, the inner surface, and the annular bottom surface of the side wall.

  In the prism glass of the present invention, in addition to the inner surface of the translucent top plate, a resin layer containing a luminescent substance is formed on any of the outer surface, the inner surface, and the annular bottom surface of the side wall. It is possible to increase the luminous efficiency from the whole and make it stand out sufficiently as a shining design. Moreover, even when the transmittance of the light transmitting surface is increased, an appropriate light emission intensity can be obtained by light emission of the resin layer formed with the outer surface, the inner surface, and the annular bottom surface of the side wall.

  In the prism glass of the present invention, it is preferable that the visible light transmittance of the translucent region of the top plate portion on which the resin layer is formed is 70% or less.

  When the film thickness of the resin layer containing a luminescent substance is 60 μm or more, the transmittance is almost 0%. Alternatively, when the white paint used for the glass block is applied after being primed, the transmittance becomes 0%. On the other hand, if the visible light transmittance of the light-transmitting region of the top plate portion exceeds 70%, the light emitting material of the resin layer is reduced, so that the light emission efficiency from the top plate portion is low, which is sufficient as a design for shining the top plate portion. It becomes difficult to make it stand out. In the prism glass of the present invention, it is important that the visible light transmittance of the translucent region of the top plate is in the range of 0 to 70%. Specifically, the visible light transmittance including a layer containing a light-emitting substance formed on a light-transmitting surface and glass can be adjusted in a range of 0 to 70%. The visible light transmittance is adjusted by adding lacquer thinner to a synthetic resin paint containing a luminescent substance. The addition ratio of the lacquer thinner to the synthetic resin paint is in the range of 1: 1 to 1: 3, and the visible light transmittance is adjusted by the combined use with the contact time of the lacquer thinner. In addition, when the visible light transmittance of the translucent region of the top plate portion is less than 30%, the resin layer becomes a design surface by the light emitted and the reflected light of the external light. It has a different appearance in terms of diffusivity.

  In the prism glass of the present invention, the resin layer is preferably colored with a pigment.

  When a pigment is not contained in the resin layer containing a luminescent substance, the coloring is limited to a combination of the luminescent substance and the resin. In the prism glass of the present invention, by providing a resin layer colored with a pigment, various color tones are possible, and it is possible to realize a lustrous design surface having a desired color.

  In the prism glass of the present invention, the light emitting substance of the resin layer is preferably a mixture of a phosphorescent substance and a fluorescent substance.

  When only a phosphor is used as the luminescent substance, no light is emitted in an environment where external light is extremely weak. Further, when only a phosphorescent substance is used as the luminescent substance, high luminous efficiency cannot be expected if the amount contained in the resin layer is small. In the prism glass of the present invention, if the light emitting substance of the resin layer is a mixture of a phosphorescent substance and a fluorescent substance, even at the time of turning off in a dark black night or indoor dark environment, at the time of a sudden power failure, Emission efficiency from the entire prism glass is increased by continuing to emit light for a considerable length of time due to the afterglow of the phosphorescent phosphor, and the fluorescent substance exerts a light emitting action due to the afterglow of the phosphorescent phosphor and weak external light. It becomes possible. Specifically, the resin layer is a synthetic resin paint containing an alkyd resin as a main component and a pigment and an organic solvent added, and containing a light-emitting substance such as a phosphorescent material and a fluorescent material. A commercial product is used for the synthetic resin paint. For example, “Product Name: Color Luminous Paint” manufactured by Shinroihi Co., Ltd. Alkyd resins are quick to dry, require no heating and slow cooling steps, are excellent in production cost, and have good weather resistance.

  In the prism glass of the present invention, the thickness of the resin layer containing the luminescent material formed on any of the outer surface, the inner surface, and the annular bottom surface of the side wall is preferably 30 μm or more, and is formed on the inner surface of the top plate portion. More preferably, the thickness of the resin layer containing the luminescent substance is 30 μm or more.

  In the prism glass of the present invention, the resin layer containing a light-emitting substance formed on the inner surface of the translucent top plate portion is provided with a resin layer, and the top plate portion maintains a certain degree of translucency. In this case, the thickness of the resin layer is limited to less than 30 μm (however, the thickness of the transparent protective layer formed by the clear paint is excluded). On the other hand, the resin layer containing a luminescent substance on any of the outer surface, the inner surface, and the annular bottom surface of the side wall can be thickened as long as the size and cost are allowed. It is possible to increase the luminous efficiency of the light and make it stand out sufficiently as a shining design. Furthermore, by increasing the resin layer formed on any of the outer surface, the inner surface, and the annular bottom surface of the side wall so as to differ by 30 μm or more compared to the thickness of the resin layer on the inner surface of the top plate, the luminous efficiency can be sufficiently increased. It becomes possible. Specifically, the standard thickness of the resin layer provided other than the inner surface of the prism glass top plate is about 100 μm. Furthermore, if a similar white paint is overcoated, a concealing effect is produced, the brightness is increased, and strong light emission is obtained.

  In the prism glass of the present invention, it is preferable that the resin layer formed on the inner surface of the top plate portion exhibits a texture in which small regions with high translucency are dispersed and distributed.

  Forming a resin layer with a texture in which small areas with high translucency are dispersed and distributed on the inner surface of the top plate part is not homogeneous translucency, but translucent of the top plate part with a resin containing a luminescent substance. In the region, a fine pattern is formed so as to obtain a light-transmitting non-uniform appearance. A colored resin layer containing a luminescent substance shields daylight (sunlight), and thus causes a decrease in daylighting (indoor illuminance). However, the resin pattern containing the luminescent substance has a thickness sufficient for light emission. The portion where there is almost no resin is high enough to have translucency close to that of glass alone. Therefore, it is possible to effectively use the transmitted light, and it is possible to realize an unprecedented and unique design surface that the entire light-transmitting region of the top plate shines although the total area to emit light is small. .

  Moreover, in the prism glass of the present invention, the annular bottom surface is sealed with a plate-like body, and the fluorescent and phosphorescent coating film is affected by the inner surface condensation, so that the heat insulating property of the prism glass itself is improved and the coating film is Since it can prevent deteriorating, it is preferable. As the plate-like body, a glass plate, a metal plate, a resin plate, or the like can be used, and a transparent plate-like body is used when the lighting or illumination effect is intended.

  In addition, since the desiccant is contained inside the prism glass, it is possible to remove moisture trapped when sealed with a plate-like body, absorb moisture that penetrates through the plate-like body and adhesive for a certain period of time, It is preferable because the humidity inside the hollow can be suppressed. As the desiccant, commercially available ones such as calcium chloride, calcium oxide, silica gel and the like may be used. The particle diameter is preferably in the range of φ0.5 mm to φ3 mm from the viewpoint of satisfying the dehumidifying performance and not very noticeable.

  In the prism glass of the present invention, when the fluorescent and phosphorescent coating film is thick in a single layer, unevenness is likely to occur, which is not preferable in terms of design and yield is not good. In the prism glass of the present invention, a resin layer containing a luminescent substance is formed on a plate-like body that seals the annular bottom surface, thereby ensuring a desired coating thickness on the two surfaces of the prism inner surface and the closing plate. A high-strength prism glass can be realized.

  The method of manufacturing a prism glass according to the present invention includes a bottomed and uncovered prism glass having a translucent top plate portion, a side wall extending downward from the periphery of the top plate portion, and an annular bottom surface of the side wall. In the manufacturing method, a resin layer containing a luminescent substance is injected into the inner surface of the prism glass, and the prism glass is tilted and / or rotated to adhere the resin to the glass surface to form a resin layer. It is characterized by.

  In the production method of the present invention, an appropriate amount of a resin liquid containing a luminescent substance is injected into the inner surface of the prism glass, and the prism glass is tilted and rotated to adhere the resin to the glass surface without incurring a large equipment cost. A resin layer having a desired thickness can be easily formed.

  The prism glass manufacturing method of the present invention is a method in which a resin layer having a texture in which small regions with high translucency are dispersed and distributed on the inner surface of the top plate by attaching a synthetic resin containing a luminescent substance. It is preferable to form.

  When a synthetic resin paint containing a luminescent substance is brought into contact with the inner surface of the prism glass, a luminescent substance such as a phosphorescent material or a fluorescent material is precipitated due to the water-repellent or oil-repellent effect on the surface of the glass, so It is possible to easily form a unique texture in which small regions with high translucency are dispersed and distributed.

  The prism glass structure according to the present invention includes a top plate portion having translucency, a side wall extending downward from the periphery of the top plate portion, and a bottomed and uncovered prism glass having an annular bottom surface of the side wall, A prism glass comprising: a support frame that supports the prism glasses arranged in alignment with a portion where a light transmitting portion is formed; and a joint portion that is positioned between the prism glasses and between the prism glass and the support frame. The prism glass has a structure in which a resin layer containing a luminescent substance is formed on the inner surface of the top plate.

  By using a prism glass structure in which a prism glass formed with a resin layer containing a luminescent substance on the inner surface of the top plate is fixed to a support frame, it has excellent durability and fading as a light emitting layer, and for a short period of time. It is possible to form a prism glass panel or wall surface having a desired light-emitting layer with a large number of options.

  Moreover, the prism glass structure of the present invention is preferably formed by forming a resin layer containing a luminescent substance on any of the outer surface, the inner surface, and the annular bottom surface of the side wall of the prism glass.

  Increasing the luminous efficiency of the entire structure of the prism glass panel, floor surface, wall surface, etc. by forming a resin layer containing a luminescent substance on any of the outer surface, inner surface and annular bottom surface of the side wall of the prism glass. Is possible.

  According to the prism glass of the present invention, it is possible to sufficiently incorporate outside light such as natural light by increasing the visible light transmittance of the resin layer containing the light-emitting substance on the light-transmitting surface, and obtain appropriate illuminance indoors. Can do. In addition, when phosphorescent phosphors are used as luminescent substances, even if the lights are turned off at night or sudden blackouts occur, light is emitted for a while due to the afterglow of the phosphorescent phosphors, and the prism glass is lit up at night by the luminous action of the phosphors. Even at the point in time, since it emits light stronger than the surroundings, a unique taste can be obtained.

  In addition, according to the method for producing prism glass of the present invention, it is possible to efficiently and easily produce prism glass having a desired light-emitting layer that has excellent durability and fading as a light-emitting layer and is manufactured in a short period of time and has many options. Become.

  Furthermore, the prism glass structure of the present invention is useful for preventing accidents because the prism glass emits light so that the presence of walls, floors or stairs can be easily recognized even in the dark.

  Below, the prism glass of the present invention, its manufacturing method, and an example of a prism glass construction are explained using figures. FIG. 1 is an explanatory view of the prism glass, and FIG. 2 is an appearance of the prism glass. FIG. 3 is an explanatory view of a prism glass manufacturing method, FIG. 4 is an explanatory view of another prism glass, and FIG. 5 is an explanatory view of a prism glass construction. In the figure, 10 is a prism glass, 11 is a resin layer containing a luminescent substance on the inner surface of the top plate portion, and 12 is a resin layer containing a luminescent substance on the outer surface, inner surface or annular bottom surface of the side wall.

  As shown in FIG. 1, the prism glass 10 of the present invention is a prism glass body having a size of 120 × 120 × 40 mm and having a bottomed and uncovered box shape with an average thickness of 15 mm. A light emitting layer 11a having an average thickness of about 15 μm containing a luminescent substance and a pigment mixed with a phosphorescent material and a fluorescent material, and a transparent protective layer 11b formed of a clear coating material of about 10 μm on the inner surface 10b of 10a The configured light emitting resin layer 11 is formed, and the visible light transmittance of the light transmitting region of the top plate portion 10a is about 60%. As shown in FIG. 2, the resin layer 11 has a texture in which small regions with high translucency are dispersed and distributed, and has an appearance similar to shoji paper. Further, a resin layer 12 having a thickness of about 100 μm is formed on the outer surface 10d, the inner surface 10e, and the annular bottom surface 10f of the side wall 10c of the prism glass 10. Furthermore, when a similar white paint is overcoated on the resin layer 12, the brightness increases due to the concealment effect of the coating film 13, and the light emission becomes stronger.

  For the light-emitting resin layers 11 and 12 of the prism glass 10, “trade name: color nocturnal paint” manufactured by Shinroihi Co., Ltd. containing a luminescent substance such as a phosphorescent material and a fluorescent material is used. In the resin layers 11 and 12, light energy is repeatedly stored with an exposure time of about 3 to 5 minutes, and light emission with an effective intensity that can be recognized in the dark continues for about 30 minutes. The light emitting resin layers 11 and 12 emit a bright fluorescent color colored with a pigment in daylight (natural light) and soft light in the dark.

  Next, a method for manufacturing the prism glass 10 will be described.

  As a synthetic resin paint containing a luminescent substance that forms the light-emitting resin layers 11 and 12, “trade name: color nocturnal paint” manufactured by Shinroihi Co., Ltd. is used. This product is a synthetic resin paint mainly composed of alkyd resin, pigment and organic solvent added. It contains luminous materials such as phosphorescent material and fluorescent material, and the surface of the coating film that stores light such as lighting is dark. It is a luminous luminous luminous paint.

  Next, as shown in FIG. 3A, after preparing a prism glass body 20 having a bottomed and uncovered box shape having a size of 120 × 120 × 40 mm and an average thickness of 15 mm, the prism The synthetic resin paint P described above is injected into the light transmitting surface 20a on the bottom surface in the recess of the glass body 20, and the paint P is spread over the entire surface. Further, as shown in FIG. 3 (B), the same weight of lacquer thinner is injected, and the prism glass body 20 is tilted or rotated to dilute the paint, and as shown in FIG. 3 (C), Drain excess. By this operation, a light-emitting substance such as a phosphorescent material and a fluorescent material is precipitated, and a unique texture is formed in which a small area with high translucency is dispersed and distributed on the translucent surface 20a, and has an appearance similar to shoji paper. It becomes like this.

  Next, the translucent surface 20a is masked with an adhesive tape or the like, and the other surface is painted using a brush, a roller or a spray gun. After naturally drying for about 1 hour, top coat with the same white paint.

  Finally, the light-emitting prism glass 10 was obtained by coating the dried synthetic resin paint P on the light transmitting surface 20a in the same manner without diluting the clear paint Q.

  As shown in FIG. 4, the prism glass 30 of Example 2 is a prism glass having a bottomed and uncovered box shape with a size of 120 × 120 × 40 mm and an average thickness of 15 mm. A light emitting resin comprising an inner surface 30b of 30a and a light emitting layer 31a of about 15 μm containing a luminescent material and a pigment mixed with a phosphorescent material and a fluorescent material, and a transparent protective layer 31b formed of a clear paint of about 10 μm. The layer 31 is formed, and the visible light transmittance of the light transmitting region of the top plate portion 30a is about 60%.

  In the prism glass 30, the light emitting resin layer 31 is formed only on the inner surface 30 b of the top plate portion 30 a, and light emission is weaker than that of the prism glass 10 of the first embodiment. Such a weak light emission prism glass 30 is useful when a design surface is produced by faint light emission, or when a pattern with a contrast of light emission intensity is formed in combination with the strong light emission prism glass 10.

  Next, an example of a prism glass construction using the prism glass 10 of the present invention will be described.

  As shown in FIG. 5, the prism glass construction body 40 has a frame-like spacer 42 placed on an edge 41 a of a lattice frame 41 made of cast iron, the prism glass 10 is placed thereon, a waterproof mortar 44 on the joint 43, By forming the waterproof layer 45 and the waterproof decorative mortar 46 in this order, the prism glass panel 47 is produced, then brought into the field, fixed to the housing 48 and applied. In addition, after attaching the lattice frame 41 to the housing 48, the prism glass panel 47 may be produced and applied in the same manner as described above.

  The prism glass structure 40 constructed in this manner can sufficiently take in outside light such as natural light to obtain an appropriate illuminance indoors, and when a phosphorescent phosphor is used as a luminescent substance, it is extinguished at night. Even after a sudden power failure, the phosphorescent phosphor emits light for a while, and the phosphor emits light more intensely than the surroundings even when the prism glass is lit up at night. It was something that could be done.

  As shown in FIG. 6, another prism glass 50 of the present invention is a prism glass body having a size of 120 × 120 × 40 mm and having a bottomed and uncovered box shape with an average thickness of 15 mm. A transparent protective layer 51b formed on the inner surface 50b of the plate portion 50a by a light emitting layer 51a having an average thickness of about 15 μm containing a luminescent substance and a pigment mixed with a phosphorescent material and a fluorescent material, and a clear paint having a thickness of about 10 μm. And the visible light transmittance of the light transmitting region of the top plate portion 50a is about 70%. The light emitting resin layer 51 has a texture similar to shoji paper with a texture in which small regions with high translucency are dispersed and distributed. A light emitting resin layer 52 having a thickness of about 100 μm is formed on the outer surface 50d, the inner surface 50e, and the annular bottom surface 50f of the side wall 50c of the prism glass 50. Furthermore, when a similar white paint is overcoated on the light emitting resin layer 52, the brightness increases due to the concealment effect of the coating film 53, and the light emission becomes stronger. A polycarbonate closing plate 54 is adhered and sealed to the annular bottom surface 50f with a silicone-based alcohol-type adhesive 55, and the inner surface 54a is a luminescent material in which a phosphorescent material, a fluorescent material, and a clear paint are mixed. In addition, a resin layer 54b having an average thickness of about 30 μm including the pigment is formed, and the visible light transmittance is about 70%. In addition, about 3 g of silica gel having a particle diameter of about 1.7 mm is placed on an inconspicuous part such as the inner surface 50e of the side wall 50c of the prism glass 50 or the inner peripheral surface 54a of the closing plate 54, immediately before the protective layer 51b and the like are completely dried. It is attached by sprinkling over and sealed. The prism glass 50 can prevent the coating film from deteriorating by preventing the fluorescent and phosphorescent coating film from being affected by condensation and improving the heat insulation of the prism glass itself. Further, when the fluorescent or phosphorescent coating film is made thick with a single layer, unevenness is likely to occur, and it is not preferable in terms of design, and the yield is not good, but the inner surface 50b of the prism glass 50 and the inner surface 54a of the closing plate 54 By securing a desired coating thickness on these two surfaces, the prism glass 50 with high emission intensity can be obtained.

  As shown in FIGS. 7A and 7B, the prism glass construction body 60 of the present invention is a portion in which a window portion 61a is formed as an opening portion of a lattice frame 61 made of cast iron fixed to a housing not shown.

A joint 66 filled with a waterproof mortar 65 and a waterproof cosmetic joint mortar 64 is formed between the prism glasses 50 and 50 and between the prism glass 50 and the lattice frame 61.

  When a prism glass having a size of 200 mm × 200 mm × 50 mm is used, as shown in FIG. 8 (A), the approximate size of the frame-shaped spacer 62 of the present invention is 216 mm × 216 mm × main part height 10 mm. The planar shape shown is a square top surface 50a, a side wall surface 50b extending downward from the periphery of the top surface 50a, and a side wall surface 51b of a prism glass 50 having an annular bottom surface 50c. It has an L-shaped surface portion 62a formed by a vertical wall portion 72b and a horizontal plate portion 62c having a width of 14 mm and a thickness of 5 mm that is in contact with the annular bottom surface 50c, and the inside of the vertical wall portion 62b and the horizontal plate portion 62c. At the intersection, a recess 62d having a diameter of 3 mm in cross section, an opening of about 2 mm and allowing the adhesive to flow in and the shape of the cured product to be locked after the adhesive flows in is formed. Those which are. On the inner surface of the vertical wall portion 62b of the L-shaped surface portion 62a, a gradient θ of about 4 ° with respect to the perpendicular is provided so that the side wall surface 50b of the prism glass 50 can be easily fitted. Further, the bottom of the outer surface of the horizontal plate 62c is chamfered by 4 mm, the length protruding outward from the inner side of the horizontal plate 62c is 4 mm, the thickness of the base portion is 1.5 mm, A protrusion 62e having a thickness of 1 mm is formed. The material of the spacer 62 is made of soft vinyl chloride, which is low in cost and excellent in weather resistance and water resistance. The lattice frame 61 is made of cast iron. As the lattice frame 61, a synthetic resin or a metal such as aluminum, stainless steel, or steel may be used.

  In the prism glass structure 60 shown in FIG. 7, a frame-like spacer 62 is placed on an edge 61 a of a cast iron lattice frame 61, the prism glass 50 is placed thereon, a waterproof mortar 64, and a waterproof layer 65 are placed on the joint 63. By forming the waterproof decorative mortar 66 in this order, the prism glass panel is manufactured, then brought into the field, fixed to the housing, and then applied. In addition to this, after attaching the lattice frame 61 to the housing, a prism glass panel may be produced and applied in the same manner as described above.
